Every time i turn the ignition on,, a 20amp fues blow out ..the car is not starting..it will turn over but not start... the fues is in the power distibutor box only

Sorry if didn't help brb I a check something that can probs help

Check to see if your timing belt is still in tact. If it is then you may need an new alternator.

that is a dead short, the fuse saved you the ensuing fire.
there are 2 fuses or more... with that name..
old cars love to short things, no lie.
the fsm is the best thing to have, and alldata.com , 2nd.
the older that car the more true that is... and your car is 10x that.
a 1991
is the fuse in the cab BOX? NOT ENGINE BAY?
THE CAB FUSE , HAS these (USA cars, other are DIFFERENT)
no country stated (sigh)
ignition sw AM1
ignition sw AM2
ignitor 1
ignition coil (1 for 4cy, and 1 for v6 engine, unsaid)
on one car there is a IGN fuse 7.5 amps
and runs the ECU and main relay.
there are 3 engines, and drawing for all 3.

get the fsm and use that or login to alldata.com and hope
it covers your engine. (unstated)

Could be a short circuit on ignition wires or a broken ignition switch. Or a short circuit on starter wires or inside the starter motor itself.

( one question i have is every time the ignition fuse blows do i need to replace the starter relay? ) NO ! You have a dead short to ground on one of the circuits that fuse feeds. Do you know how to find a short circuit ? Video's on youtube show how. The fuse that blows ,is it IGN - A 40 amp. located in the under hood fuse/ relay center ? That fuse feeds B+ voltage to the ignition switch ,which powers up other thing's ,fuse's etc.. Not just the starter relay ! I see five other fuse's that get power from that fuse when ignition switch is in the start or run position . In the I/P fuse panel the gauges fuse #4 10amp , air bag fuse #10 10amp , turn b/u fuse #16 20amp. , Plus trans fuse #20 10 amp ! Pull out these fuse an try to start the van. if the ignition fuse doesn't blow the problem is in one of these other fuse circuits. There is one more fuse that get's B+ power from the ignition switch and ign A fuse ,crank fuse fuse #8 10amp. this powers the control side of the starter relay .
You can find a free wiring diagram here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine . Under system click engine , under subsystem click starting. Click the search button then the blue link.
If you pull those fuse's i mention and it still blows the fuse look for a shorted ignition switch or wiring from ignition to the starter relay , not the relay itself. Park neutral safety switch . Isolate the circuit , pull the relay out of it's socket ,pull the crank fuse #8 in the I/P fuse box. with a ohm meter check to see if that part of the circuit is shorted to ground. Do you know how to do that ? Do you have a volt ohm meter ? You can buy one cheap at parts store .

More than likely you have an internal fault either in the fan itself or the thermostat that activates it.

For a fuse to blow it has to have a lot higher than normal current draw through it, which is normally refered to as a short. If the fuse blows almost immediately then I would suggest you unplug the fan, and see if the fuse blows with just the thermostat in the circuit. If it blows - replace the thermostat control. If it doesn't blow, plug in the fan and watch it. If it trys to start and then blows the fuse, replace the fan motor.

Which fuse does it blow? do a wiggle test to wires that comedown from ignition switch.the component fuse would give us a clue. does vehicle start with fuse blown?

something connected too ignition sdwitch has short to ground. remove all fuses except 20amp that blows turn on ignition see if blows. if not replace one by one till it does to isolate circuit. which fuse is blowing and where is it located.

Sounds like the fuel pump could be shorted or seized. I would begin troubleshooting there. It may need replacing.

First I suggest confirm what fuse blowing there and waht circuit and edevices are controled, check some wire broken or bad ground in the line and switch (if have one there).

Keep us updated.
